(54) Surgical instrument shafts and methods of manufacturing shafts for surgical instruments


(57) A surgical instrument includes a shaft (312) formed via extrusion. The shaft has one or more lumens (314,316) extending therethrough. The lumen(s) each define a cross-sectional configuration. An end effector (100) assembly is coupled to a distal end of the shaft. One or more components are coupled to the end effector assembly. The component(s) extend proximally from the end effector into the lumen(s) of the shaft. One or more of the components is formed via stamping. The component(s) define a cross-sectional configuration substantially complementary to the cross-section configuration of the lumen into which they extend.
